Hello everyone, I scripted a card with this effect:
Eidolon - Shiva
When a "l'Cie" or "Eidolon" monster you control attacks and your opponent activates a card effect: You can discard this card from your hand; negate the activation of that card and if you do, destroy it.

However, when I have this card in my hand I get the error message "47: attempt to index a nil value"
That's the function:


I don't know what's wrong there. Help appreciated. Thanks! :)

you put the cndition that allow this card act on hand?

What is line 47 of the script?

Of course. This problem is not about the condition -.-

What is line 47 of the script?

Ups, stupid me, I should have indicated that :D
Line 47 is bold:


I don't get which nil value is meant...
